Ocular Imaging Laboratory

The Ocular Imaging Laboratory developed image-based technologies for passive eye monitoring, and applied those technologies to scientific problems both basic and applied.  The P.I., Jeff Mulligan collaborated with Dr. Scott Stevenson at the University of Houston College of Optometry, to refine the use of reverse-correlation to discover subtle changes in eye movements produced by different types of visual stimuli.  The results informed models of oculomotor control used to predict behavior in dynamic environments, such as those encountered while piloting aerospace vehicles.

Much of the work of the lab was performed with the help of QuIP, an in-house developed software project for “Quick Image Processing” using an interpreted scripting language.  QuIP was used to implement apps for vision testing and fatigue assessment.  QuIP was freely available under the NASA Open Source Agreement.
